more to know


PRO mist

This leave-in lightweight mist strengthens hair’s defense prior to damaging chemical services. Powered by the K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds to renew strength and elasticity in just 4 minutes.

pH level of 7.5-8.0 shifts the cuticle layer open to deliver the K18PEPTIDE™ to damage sites on the molecular level.


PRO mask

This leave-in treatment mask does cleanup duty after damage caused during bleaching, chemical services, and heat. Powered by the K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds to renew strength and elasticity in just 4 minutes.

pH level of 5.0-6.0 helps close down the cuticle to seal in the K18PEPTIDE™ for lasting strength + elasticity.

key benefits

  • In cases of extreme damage or certain salon services, the mist works alone to renew hair without weighing it down.
  • Powered by the patented K18PEPTIDE™, engineered over 10 years in a biotech lab to work on the molecular level to rebuild hair from the inside out in just 4 minutes.
  • Because the K18PEPTIDE™ works at the molecular level, it works on every single hair type
  • Clinically proven to reverse hair damage from: Bleach + Color, Chemical Services, Heat
  • Restores strength, softness, smoothness, and bounce
  • Immediate + progressive results
  • Vegan, color-safe, cruelty-free
  • With just one salon treatment using the K18 PRO service (PRO mist + PRO mask), hair is restored up to:

91% original strength*
94% original elasticity*

*Results observed in a clinical study while using mist and mask as part of a bleaching treatment. Results may vary depending on hair type, quality, and history.

how to use

How to use with a chemical service:

  1. Turn trigger to "on" position.
  2. Prior to your service, mist hair with water (do not saturate).
  3. Section dry hair into 4 quadrants
  4. Apply 4-9 sprays of K18 PRO mist per quadrant based on length and density
  5. Let sit for 4 minutes. Do not rinse out.
  6. Dry hair if needed, then perform desired chemical service.
  7. Shampoo, do not condition.
  8. Towel-dry thoroughly.
  9. Begin with 1 pump of K18 PRO mask and add more as needed depending on length, thickness, and condition. Work evenly into hair from ends to roots, one pump at a time, maximum dosage is 3 pumps.
  10. Let sit for 4 minutes to activate. Do not rinse out.
  11. Then comb, add product + style as usual.
  12. Use for the first 4-6 washes, then as needed.

How to use as part of a styling service or as part of a K18 PRO service standalone treatment:

  1. Before haircuts, styling, or using as a treatment, cleanse hair with K18 detox shampoo for the cleanest canvas. Do not condition.
  2. Towel dry thoroughly
  3. Turn trigger to "on" position.
  4. Section hair into 4 quadrants
  5. Apply 4-9 sprays of K18 PRO mist per quadrant based on length and density
  6. Immediately apply K18 PRO mask on top (remember it’s highly concentrated so only use about 1-3 pumps).
  7. Wait 4 minutes, style as usual.

how to optimize K18

  • DO clarify before K18 if your client is a heavy product user (demineralize for mineral + metal buildup)
  • DO apply a generous amount of the PRO mist, Don’t overdo it with the mask—less is more
  • DO apply K18 mask on clean, damp hair (think about 65% wet)
  • DON’T use conditioner before applying K18 mask (you can apply after the 4 min but most find they don’t need it)
  • DON’T rinse it out
  • DON’T mix into your bleach or color
  • DON’T increase your bleach volume or alter your typical color formula

how K18 works

Traveling into the innermost layers of hair, our K18PEPTIDE™ renews strength along the width AND length of hair for lasting strength where it matters.

got questions?

Get started here

How does it work?

It’s super simple, both formulas have our biotech-powered peptide, so by using both one on top of the other, you’re doubling down on the peptide for maximum damage repair. The K18PEPTIDE™ reverses hair damage in 4 minutes by reconnecting breaks in the hair fiber along both the length (keratin chains) and the width (disulfide bonds) for holistic hair renewal.

who is it for?

K18 is engineered to work with every hair type, in every service, and with every routine.

Why do I mist hair with water before using the PRO mist?

Water will swell the cuticle layers to open up the hair fiber and allow for maximum penetration of the PRO mist into the innermost layers of hair. In the same way a damp sponge absorbs more water, damp hair absorbs K18PEPTIDE™.

Will using toner on top of K18 mask affect my client’s color?

K18 will not interfere with toner or final color. Colorists tell us K18 mask delivers a more uniform, and vibrant color application, as it evens out the hair’s porosity and damage.

is K18 PRO mist + mask considered a protein?

K18 PRO mist + mask are not protein treatments, our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by chemical, color, and heat damage. If your clients are experiencing dry, brittle hair, use PEPTIDE PREP™ detox shampoo pre-K18 mask to remove buildup.

Great product

I really enjoy the delivery of this product. Spray on lightly water misted hair, go mix your color and it's ready to go. Apply the mask after shampooing your color out. No capping and sitting under the dryer. Just give it a few minutes and your ready to complete your guests service. Smooths hair shaft and closes rough ends for those clients that only want a "whisker" trim. My only reason for 4 stars is the price of the mist. I would like to use a little more on each guest but I try to be conservative with the amount of product just because of the mist cost vs. what I charge my guest. Will continue to keep this set on hand!

Faulty pump on the cream?

Easy to use with the exception of the cream, I’ve had to shake excessively to get the pump primed on the cream. Once I think I get it working I have to start all over again for the next client.

Thank you for your review Beth. I’m sorry to hear you’re having issues. Very often an air bubble will form inside the product container causing what seems to be a broken pump. To get the product to dispense you’ll need to cap it, turn it upside down and tap it against a hard surface 10-15 times, then try to pump it again and it should begin to work properly. If that does not work can you please include a video of you trying to pump product out and the lot number found on the bottom of the bottle to pro@k18hair.com.
